For stochastic dynamics governed by diffusion processes, a general procedure to find effective equations is the conditioning approach. In this paper, we are interested in the spectrum of the generator of the resulting effective dynamics, and how it compares to the spectrum of the full generator. We prove a new relative error bound in terms of the eigenfunction approximation error for reversible systems. We also present numerical examples indicating that, if Kramers–Moyal (KM) type approximations are used to compute the spectrum of the reduced generator, it seems largely insensitive to the time window used for the KM estimators. We analyze the implications of these observations for systems driven by underdamped Langevin dynamics, and show how meaningful effective dynamics can be defined in this setting.</jats:p>"}],"doi":"10.3390/e23020134"},{"language":[{"iso":"eng"}],"year":"2021","publication_identifier":{"issn":["0740-3224","1520-8540"]},"status":"public","date_created":"2021-04-30T11:54:03Z","date_updated":"2022-01-06T06:55:20Z","file_date_updated":"2021-04-30T11:59:16Z","_id":"21932","intvolume":"        38","author":[{"orcid":"0000-0002-6331-9348","last_name":"Hammer","id":"48077","first_name":"Manfred","full_name":"Hammer, Manfred"},{"full_name":"Ebers, Lena","first_name":"Lena","last_name":"Ebers","id":"40428"},{"last_name":"Förstner","id":"158","first_name":"Jens","full_name":"Förstner, Jens","orcid":"0000-0001-7059-9862"}],"department":[{"_id":"61"},{"_id":"230"}],"citation":{"ama":"Hammer M, Ebers L, Förstner J.

This task can be understood as the inverse problem of multiobjective optimization, where the goal is to find the objective function vector of a given Pareto set. To this end, we present a method to construct the objective function vector of an unconstrained multiobjective optimization problem (MOP) such that the Pareto critical set contains a given set of data points with prescribed KKT multipliers. If such an MOP can not be found, then the method instead produces an MOP whose Pareto critical set is at least close to the data points. The key idea is to consider the objective function vector in the multiobjective KKT conditions as variable and then search for the objectives that minimize the Euclidean norm of the resulting system of equations. By expressing the objectives in a finite-dimensional basis, we transform this problem into a homogeneous, linear system of equations that can be solved efficiently. Potential applications of this approach include the identification of objectives (both from clean and noisy data) and the construction of surrogate models for expensive MOPs."}],"doi":"10.1007/s10898-020-00983-z","title":"Inverse multiobjective optimization: Inferring decision criteria from data","main_file_link":[{"url":"https://link.springer.com/content/pdf/10.1007/s10898-020-00983-z.pdf","open_access":"1"}],"oa":"1","user_id":"47427","type":"journal_article","publication":"Journal of Global Optimization","page":"3-29","volume":80,"intvolume":"        80","author":[{"full_name":"Gebken, Bennet","first_name":"Bennet","id":"32643","last_name":"Gebken"},{"orcid":"https://orcid.org/0000-0002-3389-793X","id":"47427","last_name":"Peitz","full_name":"Peitz, Sebastian","first_name":"Sebastian"}],"department":[{"_id":"101"}],"citation":{"ama":"Gebken B, Peitz S.

Here, domain experts can guide the choices of tasks and decisions with their knowledge. Nevertheless, this knowledge needs to match the situation of the company (e.g., financial resources) and the application domain of the product/service (e.g., mobile app) to reduce the risk of developing ineffective business models with low market penetration. This is not covered by one-size-fits-all development methods without tailoring before the enaction.\r\nTherefore, we conduct a design science study to create a situation-specific development approach for business models. Based on situational method engineering and our previous work in storing knowledge of methods and models in distinct repositories, this paper shows the situation-specific composition and enaction of business model development methods. First, the method engineer composes the development method out of both repositories based on the situational context. Second, the business developer enacts the method and develops the business model.  We implement the approach in a tool and evaluate it with a industrial case study on mobile apps."}],"project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Project Area C","_id":"4"},{"_id":"17","name":"SFB 901 - Subproject C5"}],"user_id":"47208","keyword":["Business Model Development","Situational Method Engineering","Lean Development","Kanban Boards","Canvas Models"],"citation":{"ieee":"S.

Furthermore, for vehicle-to-grid applications, bidirectional converters with transformers are generally more complex and have a higher count on semiconductor switches than transformerless solutions. However, when using non-isolated DC-DC converters within an OBC, the large common-mode (CM) capacitance comprising capacitive parasitics of the traction battery as well as explicit Y-capacitors connecting the high-voltage DC-system (HV-system) within specific HV-loads to ground has to be considered. For the PFC front-end stage, when supplied from the three-phase mains this means that generation of high-frequency and high-amplitude CM voltages, as it is common e.g. with the conventional six-switch full-bridge converter, has to be strictly avoided. For this reason, a modified topology is suggested leading to a different mode of operation and to a very low common-mode noise behaviour: The three-phase four-wire full-bridge PFC with split DC-link, whose midpoint is connected to the mains neutral provides very stable potentials at the DC-link rails and therefore it can be classified as Zero-CM-topology.For dedicated single-phase operation, as required for most OBC, an additional balancing leg may be added to the topology to reduce the required DC-link capacitance and allow non-electrolytic capacitors.The function of the bidirectional Zero-CM three-phase four-wire full-bridge PFC was verified by simulation and on an 11 kW-laboratory sample. The power factor is above 0.999 and an efficiency of 98 % is measured."}],"doi":"10.1109/apec42165.2021.9487462"},{"date_created":"2022-01-28T14:11:06Z","publication":"IEEE Open Journal of Industry Applications","publisher":"IEEE","language":[{"iso":"eng"}],"year":"2021","type":"journal_article","status":"public","_id":"29657","page":"47–63","volume":2,"date_updated":"2022-02-21T21:00:26Z","title":"Model Predictive Control of Permanent Magnet Synchronous Motors in the Overmodulation Region Including Six-Step Operation","author":[{"full_name":"Brosch, Anian","first_name":"Anian","last_name":"Brosch","id":"75779","orcid":"0000-0003-4871-1664"},{"orcid":"https://orcid.org/0000-0001-9362-8777","last_name":"Wallscheid","id":"11291","full_name":"Wallscheid, Oliver","first_name":"Oliver"},{"last_name":"Böcker","id":"66","first_name":"Joachim","full_name":"Böcker, Joachim","orcid":"0000-0002-8480-7295"}],"doi":"10.1109/OJIA.2021.3066105","intvolume":"         2","citation":{"apa":"Brosch, A., Wallscheid, O., &#38; Böcker, J.

One solution for a power factor correction (PFC) rectifier that is capable to operate with a non-isolated DC-DC converter, is the three-phase four-wire full-bridge PFC, with split DC-link, whose midpoint is connected to the mains neutral. Therefore, it provides very stable potentials at the DC-link rails and accordingly can be classified as Zero-CM topology, which facilitates a common-mode-free operation. When to be operated at a single-phase supply, which is a common requirement for On-board chargers (OBCs) this topology results in the voltage-doubler PFC (V2-PFC) being characterised by a comparably large DC-link voltage ripple at mains frequency. If the DC-link capacitance shall be minimized, for instance to avoid lifetime-limited electrolytic capacitors, two more circuits in addition to the original V2-PFC are proposed for keeping the common-mode-free operation: A balancing circuit (BC), that balances the voltages over the split capacitors and a ripple port (RP), that buffers the 100 Hz power pulsation of the mains. For both circuits the available two bridge legs of the three-phase topology in single-phase operation may be utilized. A 3.7 kW laboratory sample verifies the functionality of the additional circuits in conjunction with the V2-PFC and achieves an efficiency of 95 %."}]}]
